mysql - MacOS Mojave - brew install mysql@5.7 - 用户 'root' @'localhost' 拒绝访问

Question

在 MacOS Mojave 上通过 Homebrew 软件(即 brew install mysql@5.7)安装 mysql 时，似乎成功安装会打印以下说明:

We've installed your MySQL database without a root password. To secure it run:
    mysql_secure_installation

MySQL is configured to only allow connections from localhost by default

To connect run:
    mysql -uroot

当 mysql -uroot 或 mysql_secure_installation 运行时，出现以下错误:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

如何登录mysql修改root的密码？

Answer 1

似乎通过 --password 标志使用“空字符串”密码可以解决这个问题:

mysql -uroot --password=""

或者，您可以使用 --skip-grant-tables 手动启动 mysqld:

$ mysql.server --skip-grant-tables
$ mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

最后修改密码:

mysqladmin -uroot --password="" password NEW_PASSWORD
